GATE.

srEcI'FIc 'rIoN forming part of Letters Patent No. 629,706, dated July25, 1899.

Application filed March 1, 1899. Serial No. 707,304. (No model.)

To all whom it may concern:

Be it known that I, THEODORE WoRTMAN,a citizen of the UnitedStates,residing at Chamberlain, in the county of Brul and State of SouthDakota, have invented a new and useful Gate, of which the following is aspecification.

The invention relates to improvements in gates.

The object of the present invention is to improve the construction ofgates and to provide a simple, inexpensive, strong, and durable oneadapted to be easily operated without necessitating leaving thelatch-post and capable of being opened and closed with one hand, so asto leave the other hand free.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a gate constructed inaccordance with this invention. Fig. 2 is a side elevation of the gate,the supporting-frame being in section.

Like numerals of reference designate corresponding parts in both figuresof the drawings.

1 designates a supporting-frame provided sills 2 and 3, connected byuprights 4, 5, and 6. The upper horizontal sill 2 is provided at itsupper face with a longitudinal groove 7, which forms a guide for a gate8, consisting of a lazy-tongs system of levers. The uprights arearranged in pairs at opposite sides of the horizontal beams 2 and 3, andthe pair of uprights 6 forms the latch-post and is arranged at one endof the supporting-frame. A block is interposed between the upper ends ofthe uprights 6, and the upper terminals of the uprights 4 and 5, whichare located at the other end of the supporting-frame, are connected by ahorizontal top bar 9, as clearly shown in Fig. 2 of the accompanyingdrawings. The base of the frame, which is designed to be embedded in theground, and the space between the uprights 4 and 5 are boarded over toform a casing, the gate 8 being received within the vertical portion ofthe supportingframe formed by the uprights 4 and 5 when it is open.

The lower end of the end lever 10 of the lazy-ton gs system is pivotedat 11 between the end uprights 4, and the upper end of the lever 12 isslidingly connected with the supporting-frame, being provided withlateral projections 13, arranged to slide in Vertical slots 14, formedin the end uprights 4. The

end uprights 4 and 6 are supported by inclined braces 15, which aresecured at their lower ends to the bottom beam or sill 3, which isextended, as illustrated in Fig. 2.

The gate is opened and closed by an operating-lever 16, located at oneend of the supporting-frame, adjacent to the uprights 6, and fulcrumedbetween its ends on the adjacent inclined braces 15, and the lower endof the operating-lever is connected with an oscillating lever 17 by alongitudinal bar 18, extending through the base of the supportingframeand arranged within the horizontal portion of the casing or housing. Theoscillating lever 17, which is arranged adjacent to the end uprights 4,is fulcrumed between its ends at 19 on the adjacent inclined braces 15,its lower end being connected with the bar 18 and its upper end beingpivoted to a short connecting-bar 20, which is pivoted to the gate at 21at the point of connection of the bars or levers 10 and 12. By thisarrangement it will be clear that as the operatin g-lever is oscillatedthe lazy-tongs system of levers which form the gate will be expanded andcontracted to open and close the gate. When the gate is closed, its freeor extended end is arranged within the space between the uprights 6, andit is securely held against lateral movement by the same and by thegroove of the base of the supporting-frame.

The invention has the following advantages: The gate, which is simpleand comparatively inexpensive in construction, is strong and durable,and it is capable of being readily operated to open and close it withoutrequiring the operator to follow it. The gate may be opened with onehand, and the operating mechanism is housed within the casing of thesupporting-frame and is protected by the same.

Changes in the form, proportion, size, and

IOO

the minor details of construction within the scope of the appendedclaims may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

'What is claimed is 1. The combination of a supporting-frame, a gateconsisting of a lazy-tongs system of levers and connected with thesupporting-frame at one end thereof, an operating-leverfulcrumed on thesupporting-frame at one end thereof, an oscillating lever arranged atthe other end of the frame adjacent to the attached end of the gate, abar extending beneath the gate and connecting the lower ends of thelevers, and a connecting-bar extending from the upper end of theoscillating lever to the gate, substantially as described.

2. The combination of a supporting-frame provided at one end with avertical casing or housing and having a horizontal casing or housing atits base, the latter being provided with a guide-groove, a gateconsisting of a lazy-tongs system of levers attached to thesupporting-frame, guided by the groove of the base and arranged to bewithdrawn into the vertical portion of the casing, an oscillating leverconnected with the gate and arranged at one end of the supporting-frame,an operating-lever mounted on the other end of the supporting-frame, anda connection between the levers housed within the casing at the base ofthe frame, substantially as described.

3. The combination of a supporting-frame comprising upper and lowerhorizontal beams 2 and 3, uprights 4 and 5 arranged at one end of thesupporting-frame, a latchpost arranged at the other end of thesupportingframe, and means for inclosing the spaces between the uprightsand the beams, a gate connected with the uprights 4 and consisting of alazy-tongs system of lovers arranged to fold within the space betweenthe uprightst and 5, inclined braces arranged at the ends of the frameand supporting the uprights 4 and the latch-post, the lever 17 fulcrumedon the inclined brace at one end of the frame and connected at its upperend with the gate, an operating-lever fulcrumed on the inclined brace atthe other end of the supportingframe, and connections between the leversarranged within the base of the frame, sub stantially as described.

4. The combination of a supporting-frame, a gate consisting of alazy-t0n gs system of levers and connected with the supporting-frame atone end, a lever fulcrumed at that end of the gate and connected withthe latter, the hand-operated lever located at the other end of thegate, and means for connecting the two levers to cause them to work inunison, said means being located beneath the gate, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

THEODORE WVORTMAN.
